Radial distributions of pHe. a: The median pHe increased from the renal pelvis, indicating a lower pHe in the medulla than the cortex. b: The heterogeneity of the median pHe peaked at 2 mm from the renal pelvis, and decreased farther from the renal pelvis. c: The pHe of the tumor was most acidic at a depth of 1.0–1.5 mm, which represented the tumor rim. d: The heterogeneity of the median pHe was consistent from the tumor edge to the tumor rim and decreased in the tumor core. The error bars in graphs (a) and (c) represented the standard deviation. Some distance measurements in the kidney and tumor were represented by only 1 voxel and therefore had a standard deviation of zero.
